f IMPROVEMENT IN VENTILIFTINC- ATTCHMENTS TO HEARTHS.

Speciication forming part of Letters Patent No. 161.724, dated April 6,1875 application tiled January 30, 1875.

To all whom it may concern:

Be it known that I, WILLIAM S. WINFIELD, of Cross Plains, Robertsoncounty, Tennessee, have invented a new and Improved VentilatingAttachment to Hearths, of which the following is a specification:

Figures l and 2 represent vertical transverse sections of my improvedVentilating attachment to hearths; Fig. 3, a top View of thecinder-basket detached, and Fig. 4, a front view ofthe attachment.

Similar letters of reference indicate corresponding parts.

My invention relates to a Ventilating attachment to the hearths of openfire-places or grates, by which the kindling of the lire, when the doorsand windows are closed, is greatly facilitated, the dratt increased, andthe smoking ot' the chimney completely prevented.

My invention consists of a box-shaped attachment, with hinged andconcaved lid and cinder-basket, set into the door below the grate, tocommunicate either with the story below, or by a pipe with the outsideair, for supplying the required ventilation on the opening ot' the lidfor the ready kindling of the tire, etc.

A represents .the Ventilating box or casing, which is made preferably ofrectangular crosssection, and ot' suitable sheet metal placed in thehearth of open fireplaces or gra-tes a few inches in front ofthedre-place, being provided with a top iange, a, that rests on the top ofthe brick, stone, or other material of which the hearth is made. Thehollow casing A is extended either through the iioor to communicate byits open bottoln with the story below, which is the best way in thebasement story, or connected, by a side or bottom opening, b, and theexit pipe, with the outside air, for the purpose ot' furnishing acurrent of air through the casing to the grate whenever the hinged lid Bis thrown open. The lid B is provided with side wing plates or guidesB', so that it forms an extension ofthe casing, and throws, inconnection with its interior concavity, the current of air to anyrequired point in the grate, according tothe angle of inclination atwhich the lid` is adjusted. A spring, d, or equivalent device, oftheWing-plates, secures, by its pressure on the side Walls of the casing,the position of the lid at any angle. A button, knob, or ring, 6, of thelid serves to open it for setting and throwing it back entirely, if itis desired to remove the cinder basket or box C, which is supported atthe lower part of the casing, and provided with a perforated or wirebottom for collecting the coals or lcinders which fall through the topopening when the ventilator is in use.

rIhe re may be kindled with the greatest ease, even when the doors andwindows of the room are closed, by merely opening the top of theventilator, and directing the aircurrent on the kindling-wood. Vhen thesmoke is not conveyed through the chimney, which is the case with manychimneys, especially during the kindlin g ofthe tire before it is fullyablaze, the top is opened, and the current of air, passing along thearch through the chimney, carries the smoke out, so as to relieve thechimneys from a very disagreea able and annoying feature. After the ireis burning in regular order the ventilator is closed, sufficient airbeing supplied to the iirc by the draft otI the chimney from the air inthe room, to be used again, as necessity requires, for kindling the fireor for carrying away the smoke.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent The Ventilating attachments to hearths of opentire-places or grates, composed of a hollow box or casing set into thebottom of the hearth, to communicate with the air outside of the room,and provided with a hinged or adjustable lid, with side wing-plates, forthrowing a direct current ot' air on 4the grate, substantially asspecified.

WILLIAM Y S. VINFIELD.
